Extract text from DCU files
To convert your DCU file to another format, you need Embarcadero Delphi or other Developer software.
To convert other file formats to the "Compiled Binary Unit" file type, you need software like Embarcadero Delphi or a similar tool.
A .DCU file is a Delphi Compiled Unit, a binary file generated by the Embarcadero Delphi IDE during the compilation of Object Pascal source code (PAS files). Unlike standard libraries, .DCU files are essentially intermediate binaries containing compiled code, symbol information, and interface data required by the linker.
A common issue for developers and archivists is that .DCU files are strictly proprietary and version-dependent. A .DCU compiled in Delphi 7 is binary-incompatible with Delphi 10 or 11, often resulting in the dreaded "File not found" or "Bad file format" errors when trying to link legacy components without the original source. Furthermore, because it is a binary format, you cannot simply open it in a text editor like Notepad++ to read the code.
For most users, the goal is to "convert" a .DCU back into a human-readable format. If you have lost your original source code, your best conversion target is PAS (Pascal Source) using specialized decompilers, though exact recovery is rarely perfect. for documentation or analysis, converting the binary structure to TXT (Hex/Assembly dump) is common.
Convert.Guru analyzes your DCU file, detects the exact format, and lets you read the text inside.
Users also converted DCR, DPR and JDBG files.
If you want to convert DCU file to JS, TS, PY, JAVA, CPP, C, CS, PHP, RB, GO, RS or SWIFT, you can use Embarcadero Delphi or similar software from the "Delphi Compiled Binary" category. In the File menu, look for Save As… or Export….
To convert SH, PY, KT, PS1, SWIFT, LUA, PL, JAVA, SCALA, JS, VBS or TS files to DCU, try Embarcadero Delphi or another comparable tool in the "Delphi Compiled Binary" category.
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our DCU converter.
